The invention has relation to deck lid locks for motor cars, and it consists in the novel construction and combinations of parts, as hereinafter set forth.

ln the accompanying drawings illustrating the invention, the numeral 2 designates the casing, Which is a steel stamping bent up into form and provided with the side plates 3 and l spaced apart, the inner plate 3 having end extensions 5, perforated at 6 for attachment screws 7.

Fitting and Working in the casing is the jaw or bolt 8, a tubular pivot pin 9 rotatably engaging alined perforations 10, 10, of the side plates 3 and a, and engaging perforation 11 of 'said jaw or bolt, Which has spline connection 12 With said pivot The tubular pivot pin or barrel has an end extension 13, projecting outwardly, and in line with said extension are studs 14, 1li, the latter having reduced inner extensions 15, 15, engaging perforations of the outer casing plate, and at their outer ends said studs are provided with threaded aper turcs 16.

`Fitting over the pivot pin or barrel and the studs is an escutcheon or keyhole platev 17, attachment screws 18 therefor engaging perforationsthereof and the threaded apertures of vsaid studs, a `key-lfioleg'l) being formed in said plate in line with the outer end of said barrel or pivot pin, which is provided With'diametrically opposite open end notches 20 for the reception of the diametrically opposite ,lugs 21, of a key 22, said key having a cylindrical stemv the outer end of Which engages the bore of said pivot pin or barrel. i c

L key-hole cover plate 23 is hinged to the key-hole4 plate at 2a, and iscapable of bel ing turned over the key-hole to protect the The key-hole is of mutilated circular i'orm, having diametrically opposite arcuate extensions 27, 27, which overlap the outer end of the barrel or pivot pin, and the key being inserted Within' the bore of the pivot pin or barrel, With its lugs in engagement with the barrel notches, and rotated one quarter around to Withdraw the atv or bolt Within the casing, said lugs will be moved under said arcuate extensions 27, 27, Whereby the key will be effectually prevented from Withdrawal after its movement as stated to release the jaw or holt from the locking pin or stud of the deck lid. The deck lid being closed, the key is moved onequarter around'reversely, to engage the jaw or bolt with the securing pin or stud ofthe deck lid, after which the key may be Withdrawn or removed. lllie key-hole opening is larger than the notches of the barrel or pivot pin, lapping over thesaid notches at each side thereof, whereby the key may have its lugs readily engaged with said notches. The jaw or bolt is snapped home to locking or released position by the spring 28, located at the back of the casing and engaging said jaw.

1. ln a lock, a casing, a or bolt mounted therein and having a tubular pivot pin, the outer end of which is provided with a notch, a keyhole plate secured to said, casing and having a key-hole, the marginal Wall of which is provided with an eXten- Vsion-,AV and a key insertilole Within the outer end of said-*pivot pin and having a lug engageable with said notch and adapted to be brought into registration With said eX- tension to prevent Withdrawal of the key in the position assumed inthe release of the jaw or bolt.
